{"id":"CVE-2026-61595","published":"2026-09-16T16:17:14.080","lastModified":"2026-09-16T19:17:23.510","description":"djust provides Phoenix LiveView-style reactive server-side rendering for Django with Rust-powered performance. Prior to version 1.0.7, `djust.tenants` isolation was enforced only on the HTTP path. The current tenant was stored in `threading.local()` and set exclusively by the HTTP-only `TenantMiddleware`, so on the live (WebSocket/SSE) path `get_current_tenant()` was always `None` during mount and every event handler — and the tenant-aware `QuerySet` manager failed OPEN (returned the unfiltered queryset, ignoring `STRICT_MODE`), disclosing every tenant's rows to whoever held the socket. `threading.local` was additionally shared across connections on the `sync_to_async` executor thread. This issue is fixed in djust 1.0.7. Tenant storage moved to a `contextvars.ContextVar` (per async task); the resolved tenant is bound around WS/SSE mount and every dispatch; both managers scope the base queryset once and fail CLOSED (`.none()` under the default `STRICT_MODE`); and system check S006 warns when `STRICT_MODE=False`. No known workarounds are available on the live path.","cvssScore":7.7,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N","cwes":["CWE-636","CWE-862"],"vendors":[],"products":[],"references":[{"url":"https://github.com/djust-org/djust/releases/tag/v1.0.7","tags":[]},{"url":"https://github.com/djust-org/djust/security/advisories/GHSA-3492-cvg7-9mr2","tags":[]}],"exploitRefs":[{"url":"https://github.com/djust-org/djust/releases/tag/v1.0.7","tags":[]},{"url":"https://github.com/djust-org/djust/security/advisories/GHSA-3492-cvg7-9mr2","tags":[]}],"hasPoc":true,"ai":null}
